In the Bestiary Preview, for example, they have "quick" and "rebuild" versions of a few templates, with the fast being "quick and dirty" and useable on the fly by DMs, and the more comprehensive version being more accurate but more time consuming, presumably for use in game-prep. For example, one such template is "Advanced Creature", for use instead of the advancement rules (which would be a form of comprehensive advancement). Another such template is "Giant" and another is sort of a debuff template called "Young".
